About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-40S
The AirTAC SAIJ32X475-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 435 to 475 mm window. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports precise position detection.
Equipped with a 12 mm piston rod and M10x1.25 threading, this model uses adjustable air cushions at both ends to decelerate the load smoothly. The rear adjuster acts purely as a mechanical stop to set the retract end position without requiring cylinder swaps, and it does not function as a lock to hold the load without live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-40S Is Used
Machine Changeover
Dial in the 435-475 mm retract position precisely during product family shifts without swapping physical stopper blocks.
Variable End-Stop Positioning
Adjust the rear travel limit on the fly to accommodate varying package sizes or pusher distances on a packaging line.
Sensor-Calibrated Testing
Leverage the built-in magnet for CMSE or DMSE switches to verify the adjusted end-position in automated test fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-40S the Right Cylinder?
An adjustable stroke is highly beneficial for machine setup and product changeover, allowing you to dial in the exact end-stop without adding external physical stops. For load-holding requirements without continuous air pressure, this cylinder will not suffice; you should consider the SAIL or BSAI series instead.
Because this model features a 475 mm stroke, the 12 mm rod is highly susceptible to side-loading and bending under offset loads; an external guide rail must be used to prevent premature seal wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles found on some standard cylinders.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-40S FAQ
At 0.7 MPa, the push force increases to 563 N.
The rear adjuster is a mechanical stop that allows you to shorten the nominal 475 mm stroke by up to 40 mm, creating a usable travel window of 435 to 475 mm. It requires live air to hold position and is not a locking device.
